Basically a single version of N2X software is installed on N2X controller like "Packets and Protocols 6.5 6.9" and "QuickTest 7.4" and the same version of N2X software should be installed on iTest. But multiple N2X software can be installed on the controller and we can select one of these version to connect.
If both "6.9 and 6.10" were installed on N2X controlelr and 6.9 was installed on iTest, can iTest select 6.9 controller to communicate ?
You will just get a warning message when you start the Agilent session if your client version is different than server version. You should still be able to use the session and issue commands. In cases where iTest does not support a particular N2X version, you will get a warning message too.
Note that if certain functionality is available in 6.10 and you try to use it with 6.9 client, you might get an Tcl API error saying that that method is not available.
Using N2X API, we can select a specific version on controller as following
% package require AgtClient
1.1
%
% AgtListSessionVersion RouterTester900
{6.9 System Release} {6.10 System Release}
%
% AgtOpenSessionByVersion RouterTester900 "6.9 System Release"
%
2
%
iTest(N2X 6.9 installed) automatically select supported version then connect to 6.9 controller ?
iTest does not automatically select the supported version by using the "AgtOpenSessionByVersion". It first calls " AgtGetVersion" to get the client version after loading the tcl package. Then it uses "AgtOpenSession" to open the session and connect to the chassis. Then it re-issues the "AgtGetVersion" command. If the results from two "AgtGetVersion" mismatch, we warn the user.
This might be a future enhancement where we allow users to pick version that they want to connect to by using "AgtOpenSessionByVersion".
